Question: I need ideas for my project. I have to make a math board game.What can i do?

Have to be 7th grade math skills.Can not be store bought.

Answer: Make a game with a path of squares. Squares can be plainly colored with like every third or fourth one saying something like, "go back two spaces," "move forward one space," "lose a turn," etc...
Make cards to draw out of index cards or construction paper. On each card, write a problem that has to be solved, or a word where the player has to give the definition. You will probably want to put the answer on there, so someone beside the player whose turn it is should draw and read the card.
So - roll a die, advance on squares, draw a card, answer it, you can't advance from that spot until you answer a card correctly - first one to the end wins.
You could even make the game on a large piece of butcher paper, or on a piece of poster paper.
Good luck!

Question: This is a hard math question?

"Euchre is a popular card game played with a partial deck of ordinary cards. Only 24 cards are used: the 9, 10, Jack, Queen, King, and Ace of each suit (hearts, spades, diamonds, and clubs). Consider the experiment of drawing cards from a Euchre deck until a club is drawn. After each draw the card is replaced and the deck is shuffled." Then it asks "complete the table below for a theoretical probability distribution for the number of draws to get a club. The first column in the table reads "number of draws to get first club" and the values are 1, 2, 3, 4, 5, 6 or more i'm supposed to find the probability for each value.

Answer: For every draw, there are 6 clubs out of 24 so the prob of drawing a club is 1/4.
And since you put back the card you drew, it remains 1/4.

P(first draw) = 1/4
P(second draw) = (3/4)*(1/4) (it's a 3/4 prob you didn't draw a club the first time)
P(third draw) = (3/4)^2*(1/4) (it's a (3/4)^2 prob you didn't draw a club the first and 2nd times)

In general, P(on draw n) = (3/4)^(n-1)*(1/4)
